Soonest bus is now highlighted for clarity. Users must manually click
back on the shorest arc.
WIP - Have quickFlash animation to ripple for initialization.

Need to have graphic revert back to original state when done.
Have everything changing and reverting, but timing between text and
arcs is off. Might need to redo entire transition.
Commit with comments for blogpost. Will refactor after this.
Ripple works smoother.
Major refactorage.

- renamed. many. items.
  - in the API file, changed 'routes' to 'directions' starting with
    parseXMLstops. route was to reference the multiple routes a bus line
    may have, but 'line' and 'route' are probably synonymous for most.
    so 'directions' represent the multiple paths (in/outbound from
    different origins), a bus line could take
  - css classes now are all lower-cass and use dashs
  - css ids are CapitalizedLikeThis

- removed a handful of global variables. have a routesInfo object to
  cache user lookups for the #RouteSelector change event, which
  minimizes get requests to Nextbus
Highlight is now driven by a __highlight__ flag on the selected arc
instead of checking the color.. data driven.

Implemented a pulsing response on the click handler, but will take
it out.
